Sid Meier's Civilization V has suffered from a similar bug since the release of Sid Meier's Civilization VI ;-(
Previously, there was a patch that fixed this, but the game's publisher saw fit to remove it, making the game unplayable on Linux, probably to sell more new games ;-(
However, there is a workaround.
Create a shortcut to launch this game, for example on your desktop. Right-click on it, then select properties, under "Command", add the following line :
This command will force the use of only 4 CPUs (which is more than enough to play it).
This will prevent the game from randomly crashing mid-game.
!!! But be careful, Steam must not already be running for this to work. If this is the case, you must first exit Steam, then restart it by double-clicking on the game icon !!!
This should also work with other games that have this same type of problem… But Steam will only run with 4 CPUs maximum, if you want to play another game after that, I would recommend you to quit Steam and restart it normally.
Another solution is to launch Steam with the option :

You should be able to have
taskset -c 0,1,2,3 %command% as the game's launch options in its Properties to have it apply just for that game.

Hmm, I definitely got this working maybe a couple of years ago. I think I might have been running EndeavourOS back then? But I didn't have to do anything special. The cable just appeared as an input, so I could record from it directly in things like OBS, although it was like a line in, so maybe I had to put it through my amp? I can't remember, sorry.
I'll maybe try to find it again and give it another shot.

And if Steam is already running, it won't take into account the core restriction of the number of cores we're trying to impose on it. In such a case, the game will crash. If you had tested it, you would know...
